1. Which of the following lobes of the brain is responsible for sensation, perception, and spatial reasoning?

Correct answer: C

Rationale: The parietal lobe is responsible for sensation, perception, and spatial reasoning. It plays a crucial role in processing sensory information, assisting in spatial orientation, and integrating various sensory inputs to create a comprehensive perception of the surrounding environment. The frontal lobe, although important for higher cognitive functions and motor skills, is not primarily responsible for sensation, perception, or spatial reasoning. The occipital lobe is mainly involved in visual processing, and the temporal lobe is primarily associated with auditory processing, memory, and emotions, making them incorrect choices for this question.

2. Which of the following constituents of blood is a biconcave disc that is round and flat without a nucleus?

Correct answer: C

Rationale: The correct answer is C, RBC (Red Blood Cell). Red blood cells are biconcave discs that lack a nucleus, allowing them to carry oxygen efficiently. Plasma (A) is the liquid component of blood that carries various substances. Platelets (B) are cell fragments important for blood clotting. White blood cells (WBCs) (D) are part of the immune system and have a nucleus.

3. Which of the following body systems controls fluid loss, protects deep tissues, and synthesizes vitamin D?

Correct answer: D

Rationale: The integumentary system is responsible for controlling fluid loss through sweat, protecting deep tissues as the body's first line of defense, and synthesizing vitamin D when exposed to sunlight. The skin, hair, nails, and associated glands make up the integumentary system, which plays a crucial role in maintaining homeostasis and overall health. The skeletal system (Choice A) provides structural support and protection for internal organs but does not directly control fluid loss, protect deep tissues, or synthesize vitamin D. The muscular system (Choice B) is responsible for movement and stability but is not involved in the functions described. The lymphatic system (Choice C) is primarily responsible for immunity and fluid balance, not the specific functions mentioned in the question.

4. Which of the following types of muscle tissue is found attached to bones and allows for voluntary movement?

Correct answer: C

Rationale: The correct answer is C: Skeletal muscle. Skeletal muscle is attached to bones and allows for voluntary movement, such as walking, running, and lifting objects. Smooth muscle, found in the walls of internal organs and blood vessels, is responsible for involuntary movements. Cardiac muscle is specific to the heart and controls involuntary contraction. Connective tissue, on the other hand, provides support and connects different structures in the body, but it is not responsible for voluntary movement like skeletal muscle.

5. Through which structure do the kidneys reabsorb water, salts, and nutrients and return them to the body?

Correct answer: C

Rationale: The question has been corrected to specify the structure responsible for reabsorbing water, salts, and nutrients in the kidneys. The correct answer is the nephron, which is the functional unit of the kidney that performs filtration and reabsorption processes. The renal artery brings blood into the kidney for filtration, the renal vein carries filtered blood away from the kidney, and the glomerulus is a part of the nephron where filtration occurs. Therefore, the nephron is the structure that reabsorbs substances and returns them to the body.
